You could use various WiFi/Bluetooth SDIO modules to build a IoT solution with Linux/Andriod. Cypress currently uses iMX6 UL as the reference platform for Linux and iMX6 SX for Android.
We would like to know what is the host processor you are using in your Linux IoT Solution that uses a SDIO module for Bluetooth/WiFi. Note that this poll is when you are running Linux/Andriod on your host processor and using the bcmdhd driver. This is **not** for WICED based solution.
